System information
Switch Description
Mute Excludes the selected event from playback.
Muted events are darkened on the timeline to indicate their muted
state. In the following example, the middle events are muted:
Lock Locks an event so that it cannot be moved or edited.
Loop Enabling the Loop switch on an event will allow you to drag the right
edge of the event out and have it repeat the file over and over rather
than inserting silence.
Invert Phase (audio
only)
Reverses the phase of the sound data. Although inverting data does
not make an audible difference in a single file, it can prevent phase
cancellation when mixing or crossfading audio signals.
Normalize (audio only) Maximizes an audio event’s volume without clipping.
If you want to recalculate the normalization value for the selected
event, click the Recalculate button on the Event Properties dialog to
determine the normalization value for the selected event. If you trim
or extend a normalized event, you will want to recalculate the
normalization to account for the different audio levels that may have
been exposed.
Maintain Aspect Ratio
(video only)
Prevents aspect ratio distortion (stretching of video frames) when the
length-to-width ratio between the source media and project's frame
size are not the same.
Reduce Interlace
Flicker (video only)
This switch can be useful in cases where the source material didn't
originate as video and contains extremely high spatial or temporal
frequencies.
When you watch the rendered (interlaced) output on video of this
sort of media, you may see flickering or crawling edges if this switch
is not applied
Enable this switch when using imported images that were not created
using a video camera (such as photographs) or when using
generated media or text.

on page 322 and "Creating Text and Titles" on page 327.
